Land Surveyor in Madison County, Illinois

Licensed local surveyors for property, boundary and elevation surveys anywhere in Madison County โ€” in town or out in the county.

Surveying across Madison County

Madison County covers a lot of different ground. The western edge is flat bottomland along the Mississippi, home to Granite City, Madison, Venice and the industrial corridor around Wood River and Hartford. Climb the bluffs and the county turns into older river towns like Alton and Godfrey, then commuter suburbs, then open farmland stretching east toward Highland, Marine and St. Jacob. A survey request from one end of the county can look nothing like one from the other, so we ask about the parcel before confirming a price.

All recorded land documents for the county, including deeds, plats and easements, are filed with the Madison County Recorder in the administration building in Edwardsville. The county's Maps & Plats staff keep the tax map side of the picture, and the Madison County GIS Viewer shows parcel outlines, aerials and other layers in one place. Those tools are useful for research, but parcel outlines on a tax map are approximations. A licensed surveyor on our team or in our network relies on the recorded descriptions and monuments found in the field.

Flood risk here comes from two directions. Along the river, the American Bottom sits behind levees that were rebuilt over the past decade under the Southwestern Illinois Flood Prevention District, and flood maps reflect that work. Inland, Cahokia Creek, Indian Creek and their tributaries drain much of the county's centre, and the county has worked on watershed planning for that system. An elevation certificate is the usual answer when a lender flags a building near either kind of water.

What to know about Madison County

Plat Act divisions outside cities

Madison County allows some rural land to be divided under the Illinois Plat Act instead of a full subdivision, but each new tract still has to meet county zoning lot standards. The county's Maps & Plats office can tell you whether a parcel qualifies before you order a survey.

Subdivision review in Edwardsville

In unincorporated areas, preliminary and final subdivision plats go to the county Planning & Development department in Edwardsville, which sets minimum lot sizes and road improvements. Lots inside a city follow that city's own rules instead.

Undermined ground

Large parts of Madison County sit above old underground coal workings, and the county is on Illinois' mandatory mine subsidence insurance list. A survey maps lines and buildings; questions about undermining belong with your insurer or a geotechnical engineer.

Madison County survey questions

Can I divide my rural Madison County land without a full subdivision plat?

Sometimes. The county recognises Plat Act divisions as an alternative to platting, provided every resulting tract meets the county zoning ordinance's lot requirements. Call the Maps & Plats office to confirm eligibility, then have a licensed Illinois surveyor prepare the tract survey and legal descriptions.

Is the Madison County GIS Viewer good enough to show my property line?

It is a good starting point for spotting a parcel and its neighbours, but the outlines are drawn for tax mapping and can be off by several feet or more. A boundary survey is the document that locates your legal corners on the ground.

Who handles permits and floodplain questions for unincorporated Madison County?

The county Planning & Development department in Edwardsville covers zoning, building and floodplain administration outside city limits. If your address is inside Alton, Granite City, Edwardsville or another city, that city's own staff handle those questions.

My lender says my Granite City-area home is near a levee. What survey do I need?

Ask the lender which document they want, but it is usually an elevation certificate. It records the elevation of your lowest floor and surrounding ground on FEMA's form, which helps insurers rate property in the levee-protected bottomland.
